used. If the calculated cost is less than 1, the value of 1 is used. If no cost or bandwidth reference
value is configured for an interface, OSPF computes the interface cost based on the interface
bandwidth and default bandwidth reference value.
To configure an OSPF cost for an interface:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter interface view.
interface interface-type
interface-number
N/A
3. Configure an OSPF cost
for the interface.
ospf cost value
By default, the OSPF cost is calculated
according to the interface bandwidth.
For a loopback interface, the OSPF cost
is 0 by default.
To configure a bandwidth reference value:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id
router-id | vpn-instance
vpn-instance-name ] *
N/A
3. Configure a bandwidth
reference value.
bandwidth-reference value The default setting is 100 Mbps.

Configuring the maximum number of ECMP routes
Perform this task to implement load sharing over ECMP routes.
To configure the maximum number of ECMP routes:
Step Command Remarks
1. Enter system view. system-view N/A
2. Enter OSPF view.
ospf [ process-id | router-id router-id |
vpn-instance vpn-instance-name ] *
N/A
3. Configure the maximum
number of ECMP routes.
maximum load-balancing maximum
By default, the maximum
number of ECMP routes is the
same as that configured in the
max-ecmp-num command.
For more information about the
max-ecmp-num command, see
